Java 中的 Docx 到 Pdf 转换器

Question

以下代码不适用于 Apache poi 3.16。有人可以提供正确的解决方案吗，在我的项目中有一些只使用的依赖

public void ConvertToPDF(String docPath, String pdfPath) {
    try {
        InputStream doc = new FileInputStream(new File(docPath));
        XWPFDocument document = new XWPFDocument(doc);
        PdfOptions options = PdfOptions.create();
        OutputStream out = new FileOutputStream(new File(pdfPath));
        PdfConverter.getInstance().convert(document, out, options);
        System.out.println("Done");
    } catch (FileNotFoundException ex) {
        System.out.println(ex.getMessage());
    } catch (IOException ex) {
        System.out.println(ex.getMessage());
    }
}

例外：

Answer 1

这样做的主要问题是那些 PdfOptions 和 PdfConverter 不是 apache poi 项目的一部分。它们由 opensagres 开发，第一个版本的名称很糟糕 org.apache.poi.xwpf.converter.pdf.PdfOptions 和 org.apache.poi.xwpf.converter.pdf.PdfConverter 。这些旧课程自 2014 年以来未更新，需要版本 3.9 apache poi 才能使用。

使用最新的 fr.opensagres.poi.xwpf.converter.pdf ，它使用最新的稳定版本 apache poi 3.17 。

然后做

import java.io.InputStream;
import java.io.OutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.File;

//needed jars: fr.opensagres.poi.xwpf.converter.core-2.0.1.jar,
//             fr.opensagres.poi.xwpf.converter.pdf-2.0.1.jar,
//             fr.opensagres.xdocreport.itext.extension-2.0.1.jar,
//             itext-2.1.7.jar
import fr.opensagres.poi.xwpf.converter.pdf.PdfOptions;
import fr.opensagres.poi.xwpf.converter.pdf.PdfConverter;

//needed jars: apache poi and it's dependencies
import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class DOCXToPDFConverterSampleMin {

 public static void main(String[] args) throws Exception {

  String docPath = "./WordDocument.docx";
  String pdfPath = "./WordDocument.pdf";

  InputStream in = new FileInputStream(new File(docPath));
  XWPFDocument document = new XWPFDocument(in);
  PdfOptions options = PdfOptions.create();
  OutputStream out = new FileOutputStream(new File(pdfPath));
  PdfConverter.getInstance().convert(document, out, options);

  document.close();
  out.close();

 }
}

2018 年 10 月：此代码使用 apache poi 3.17 工作。由于 --- 的变化，它不能使用 apache poi 4.0.0 fr.opensagres.poi.xwpf.converter ， apache poi 中没有考虑到这些变化。

---

2019年2月：现在使用最新的 apache poi 版本 4.0.1 版本 2.0.2 1CC400356818187D9E9549E9549F0D28D28- .

---

2021 年 6 月：使用 apache poi 版本 4.1.2 和最新版本 2.0.2 fr.po.opensavers.pdf 和 conversort.pdf 的最新版本Cannot work using apache poi version 5.0.0 because XDocReport needs ooxml-schemas which apache poi 5 does not support anymore.

---

2022年4月：使用—- 2.0.3 apache poi 版本 5.2.2

Answer 2

2021 年 6 月：使用 apache poi 版本 4.1.2 和 fr.opensagres.poi.xwpf.converter.core 和 consorts 的最新版本 2.0.2。无法使用 apache poi 5.0.0 版工作，因为 XDocReport 需要 ooxml-schemas，而 apache poi 5 不再支持它。

ooxml-schemas 已替换为 poi-ooxml-full 。

https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml-full/5.0.0

但它不适用于 fr.opensagres.poi.xwpf.converter.core 2.0.2 ，因为与 apache-poi 5.0.0 中包含的新版本 CTStyle 不兼容。
